Freight Orders

Freight deliveries require a delivery time be scheduled and someone must be present at the time of delivery to inspect and sign for the merchandise. A representative from the freight carrier will call the phone number entered at checkout to schedule the delivery.

Liftgate Service

For freight deliveries, you have the option of adding a liftgate to your delivery. A liftgate is the device that lowers a product from the truck to ground level.

CPO recommends adding liftgate service for freight deliveries exceeding 100 lbs if you do not have a loading dock or fork lift at the delivery address. Additional charges may apply. The liftgate option will be presented during the checkout process.

Please note that liftgate service only ensures the product is removed from the truck. We recommend you have the additional help of two to four people to move the product to its desired location because drivers are not required to assist.

Requesting liftgate service after ordering may result in additional charges and delays.

What A Beast!!
I went into this purchase reading alot of the reviews since I have had no experiences with a chipper/shredder. The CS4325 looked simple enough and even with its weight, it was easy to maneuver. However I must start with the one I purchased did not have the extended oil fill tube. Trying to get oil in this without making a mess is near impossible! The fill area is in a very hard to reach area. I tried numerous funnels, but none of them would fit in the tight space. I am going to have to try to manufacture something, but atleast it is not something you need to get to for every use.

With that said, and with gas added, 2 pulls and she started right up. You most DEFINITELY need ear protection!!! This thing is loud! I chose not to bag the shreddings since I was cutting up a 65 foot Maple. The other reviews weren't kidding when they said it blew an 8 foot area clean with the forced air coming from it. I started off with some small branches to just get used to it and it did a quick job. When I put in the 2-3" branches she pulled them in and spat them out like they were paper! One word of warning, you should wear long sleeves and step back a bit when you feed in long branches. She pulls them in with such force that they whip around and if there are smaller branches attached to the main one, they will hit you on their way into funnel. And trust me, they hurt!! Through the whole process of chipping up this Maple, she did not bog down at all. However, when you put leaves and small twigs in the top hopper, you need to do it judiciously. The unit has a great tendency to clog up. The stuff just doesn't make it to the blades. As others have said, it is best a keep a long stick handy to stir the hopper up so the leaves and twigs drop down in.

Other then that, she ran great and did an outstanding job. The mulch it produced is nice and fine. If you don't use the bag, make sure you point the chute to a fairly large and open area for the chips/mulch to blow to.

I highly recommend this model and actually look forward to using it again.

I have been using this machine for over two years chipping tree limbs up to and including 3 inches. I am cutting back overgrown firs, cedars, holly tree branches, overgrown rhododendron, and leaves. My blades need sharpening or replacing, and I found it difficult to get at them. No local facility had any of them in stock, and I have received the wrong blade shipments from various sources.

Over all I am very satisfied with this chipper/shredder. It has performed well with no problems in the 2.5 years I have owned it, and I have used it 4 to 7 hours a day several days in a row.

Great Purchase
This is a great unit, delivers as promised. The only two things I would like to see improved, have a larger debris bag and a set up for electric start.

What is the horse power of this engine? 250cc doesn't mean anything to me
Bob on Apr 3, 2016
BEST ANSWER: About every 32.5CC will result in 1 HP when looking at 4 cycle small engines. This number is not exact because compression ratios will vary. The trbn24b-424m766 will have about 7.5HP
